Antenna 90C4090
High gain, circularly polarized wide beam RFID antenna
The Identix 90C4090 is a Far Field UHF RFID antenna engineered for high-performance applications, with emphasis on retail loss-prevention systems (EAS – Electronic Article Surveillance).
Its fan-shaped radiation pattern was developed to provide confined reading zones, making it ideal for locations such as store entrances, corridors, and controlled passage areas, where detection accuracy is essential.
The 90C4090’s radiation lobe features a 40° horizontal beamwidth and a 90° vertical beamwidth, with a 15° horizontal tilt, optimizing coverage and reducing readings outside the desired area.
Equipped with right-hand circular polarization, high gain, and low axial ratio, the 90C4090 delivers excellent RFID tag reading performance regardless of tag orientation in the field.
Its modern, compact, and lightweight design enables simple installation and discreet integration in various environments, such as retail stores, logistics centers, industrial facilities, and corporate settings.
